This invention has relation to attachments for preventing the refillingof bottles after once being filledand emptied, and to bottles towhichsuch attachments are attached. It

is designed as an improvement upon an invention for which I have filedan application dated December 1-5. 1883; and the invention consists inthe construction and novel arrangement of devices, as will behereinafter more fully set forth, and particularly pointed out in theclaims appended 7' Referring by letter to the drawings, A des: ignates abottle of any suitable material, but preferably of clear glass, in orderto be trans parent, having cast, blown in, or otherwise formed in theneck A cavities or recesses B, directly opposite each other, which serveas receptacles for the points of the spring bolts, plungcrs, 0rhingelatches E E. These bolts secure the valve box or chamber 0 on andin the inside of the neck A of the bottle, being pressed or forcedforward into the directlyopposite cavities or recesses by U -shaped orother suitable form of spring, F

O designates the upper portion of any suitable form of valve box orchamber, having formed within its interior an inner chamber, 0, providedwith two or more cylindrical or other suitablyshaped openings, J J J,placed at or near the top of the interior chamber, 0', on the sides, andextending directly outward to the exterior circumference of the valvebox or chamber 0. These openings should have a combined area of not lessthan the area of the opening K at the bottom of the lower portion, G, ofthe valve box or chamber 0. Loose ly fitting within the interiorchamber, G, is a light, buoyant, spherical, or other shaped valve, D,made of cork or any suitable elastic material, which rests on the upperedge of the lower portion, G, of the valve-box. On the exterior of thelower portion of the upper part, 0", of the, valve box or chamber 0 iscast, pressed, or otherwise formeda screwthread to engage with a similarscrew-thread cast, pressed, or otherwise formed on the in side of thelower portion, G; or the two parts may be slipped one within the otherand fastened to each other by means of a pin or rivet passed directlythrough each. as may be deemed best.

formed on the outside of the upper portion of the valve box or chamber 6immediately be low the openings J, is fitted an elastic washer or band,H, made of rubber, cork, or other Just beneath a shoulder, G

suitable material of an elastic nature, and should be larger in diameterthan the internal diameter of the neck A of the bottle. This elasticwasher or band is intended to serve a twofold purpose: first, to make afluid-tight joint between the neck of the bottle and valvebox; and,second, to make a fluid-tight joint between the two parts 0 and G,forming the valve box or chamber 0. This prevents the passage of anyfluid around the outside of the valve box or chamber itself or betweenthe two parts forming the valve box or chamber '0 but causes the fluidcontents of the bottle, when being drawn off or poured out, to passthrough the valve-box by the opening K raising the valve D through theinternal chamber, 0.

The valve box or chamber 0 may be made of any suitable material ofproper strength and freedom from corrosion or contaminating effects onthe contents of the bottle; but I prefer making the upper portion ofglass,in order that the valve can be seenat all times.

1 0 indicates the interior chamber, formed on the inside of the upperportion of the valvebox 0, and is made of sufficient depth to containthe single buoyant valve or less buoyant valve with its float D. Thebuoyancy of this valve should be sufflcient, so that it may float withtwo-thirds or three-fourths of itself submerged beneath any fluidsimilar to the contents of the bottle in which it is in; or avalve maybe used of less buoyancy or no buoyancy at all, provided it has a floatabove it. Such valve and float is shown in Fig. 13 in section.

The object in having the valve buoyant as well as elastic, or beingelastic and not particularly buoyant, but provided with a float aboveit, is, should any one attempt refilling the bottle byinverting it orturning it mouth downward, to let the valve fall back from its seat '22,the fluid could be gently forced by the valve were it too heavy. Now,being buoyant and the fluid entering the mouth while the bottle is in aninverted position,will first fill the chamber 0, surrounding the valve;but as the fluid rises sufficiently to. cover two-thirds or more of thevalve, it floats and rises with the fluid until it closes up the openingK at its valveseat 2 2, preventing the fluid from entering the bottle. l

F designates any suitable form of spring,-

' ad, to receive the elastic band H, and the lower portion, G, of thevalve-seat is made removable and provided in 1ts outerwall withdiametrically-arranged recesses a, toreceive a having interspaces c, toform channels for the outer passage of the liquid from the bottles, theribs forming guides for the raising and falling of the valve or valvestherein.

. The mode of operation is as follows: After' the bottle has been filledin the usual manner, take the upper part of the valve-box 0, place theelastic band or washer H on the same, pressing the band well up underthe collar or shoulder 0 invert the part 0, and drop one of the valvesinto the inner chamber, 0. Then the lower part of valve-box G is screwedor secured to the upper part, 0, pressing well up against the elasticwasher or band H. Insert into the opening E the two bolts or plungers, EE. Take the U-shaped spring and insert one foot into each cavity in theend of the plungers or bolts, press the bolts with the finger and thumbwell into their openings, and insert valve box or chamber thus fittedtogether into the neck of the bottle. of the neck, being smooth, keepthe bolts compressed until the valve box or chamber is pushed down intothe bottle-neck opposite to the said cavities in the neck,when thesprings F force the bolts or plungers E E into the cavities B B, thuspreventing the removal of the said valve-box from the bottleneck. The

liquid in the bottle can be poured out, but no to the valve D closingthe opening K, and

The sides should the bottle be inverted, and an attempt be made to forcethe liquid into-the bottle while the valve has fallen away from theopening K, no better result will be obtained, for just as soon as thechamber .0 becomes filled the valve D, owing to its buoyancy, will floatup to the opening K and close it.

I do not wish to be understood as claiming in this application any ofthe devices which I have already claimed in my application, No.

with the upper and lower portions connected together, having formed onthe outside of the lower end of the upper portion a screw-thread toengage with a like thread on the inside of the outside of the bottomportion, said bottom portion to extend up on the inside of the upperportion to form a valve-seat on its edge, the valve-box with two or moreopenings directly out i to the exterior circumference and. above thecollar, under which the elastic washer or band is secured, and with twoopenings or recesses in which slide two spring locking devices forpreventing the re moval of the valve box or casing, substantially asspecified.

2. A valve-box placed in the neck of a bot tle, having a stopper orvalve and a buoyant float to prevent the refilling of a bottle, substantially as specified.

3. The combination, with a valve-box having means for securing it in theneck of a bottle, of an elastic spherical non-buoyant valve and a floatof sufficient buoyancy to lift the valve when the float is submerged orpartly submerged in fluid, substantially as and for the purposesspecified.

In testimony whereof I affix my signature in presence of two witnesses.
